HALIOTIS.— Plate T. 



With the rich and beautiful materials now before me, 

 cliiefly from the coUection of Mr. Cuming, I shaU proliably 

 be enabled to determine about eighty species ; oidy a 

 limited portion of them, however, were taken by that emi- 

 nent traveller alive, as his researches have been chiefly con- 

 fined to the Western Hemisphere. 



Species 1. (Mus. Ciuniug.) 



Haliotis PULCllEERlMA. Hal. tesid orUculari-ovatd, 

 convexuisculd, radiatim cosfatd, costis foriibus, laiiiis- 

 culis, nodoso-corrugatis, interstitiis rugosis ; spird sub- 

 ampld ; formn'mihxiH senisperviis ; lutescente-albd, cas- 

 taneo-rubeute maculatd et variegatd, intus aureo-albi- 

 cante. 



The very beautiful Haliotis. Shell orbicularly ovate, 

 rather convex, radiately ribbed, ribs strong, rather 

 wide, nodosely wrinkled, interstices rough ; spu'e 

 rather large ; six perforations open ; yellowish white, 

 spotted and variegated with chesnut red ; nacre golden 

 white. 



M.YETYN, Universal Conoh. vol. ii. pi. 62. 



Hab. Lord Hood's and Grimwood Islands, Pacific Ocean ; 

 Cuming. 



There is no green or blue either in the outer coat or 

 nacre of tliis species. The ribs are of a soft yellowish 

 wliite, stained here and there with chesnut-red, and the 

 pearly interior exhibits a faint golden hue. 



Species 2. (Mus. Cuming.) 



Haliotis glabra. Hal. testd ollongo-ovatd, conmxo- 

 plauulatd, spird parvd ; glabra, striis perpaticis ex- 

 soulptis radiaiitibus, latere sinistra tenuilirato, forami- 

 ttibus seiiis perviis, parviusculis ; labro sinistro latitis- 

 ctdo ; olivaceo-viridi, luteo-viridesceute angulato-reticu- 

 latd et variegatd. 



The smooth Haliotis. Shell oblong-ovate, convexly 

 flattened, spire small ; smooth, with a few radiating 

 engraved striaj, left side finely ridged, six perforations 

 open, rather small, left bp rather broad; dark olive 

 green, angularly reticulated and vai-iegated with pale 

 yellowish green. 



Chemnitz, Conch. Cab. vol. x. p. 311. pi. 166. f. 1603, 3. 



Hab. Australia; Dring, R.N. 



M. Deshayes is perfectly correct in his views of tliis 



species, so admLi'ably portrayed by Chemnitz. Figures 



1607 and 8 of the ' ConchyUen Cabinet ' represent a species, 



hereafter to be described, unquestionably distinct both in 

 form and colom- from that under consideration ; and the 

 shell represented by Schubert and Wagner in the Supple- 

 ment of that work, Fig. 3086, 7, as a variety aiH. glabra, 

 is also a very distinct species, subsequently described by 

 Mr. Swainson under the name of Haliotis Californiemis. 



Species 3. (Mus. Cuming.) 



Haliotis Cunninghamii. Hal. testdovatd, tenui, maxima, 

 concavo-depressd, latere sinistro angulato, ad angnlum 

 perforato,foraminibus subtubulosis, seiiis, (in testd juve- 

 ni septenis vel octorvisj perviis ; oblique undato-plicatd, 

 striis elevatis minute corrugatis midiqne sculptd, mar- 

 gine sinistro latiiisculo, planato ; exttis rubro-ferru- 

 gined, viridifuscoque variegatd, intus albicante. 



Cunningham's Haliotis. Shell ovate, thin, vei-y large, 

 concavely dein-essed, left side augulated, perforated 

 at the angle, perforations somewhat tubulous, six 

 (in the young shell seven or eight) open, obliquely 

 undidately pbcated, scidptm'ed thi-oughout with mi- 

 nutely wrinkled strife, left margin rather broad, flat- 

 tened ; outside reddish brown, vaiiegated with green 

 and darker brown, inside wliitisli. 



Gray, Appendix to King's Voyage (Narrative of a Survey 

 of the Coast of Australia, 1837), vol. ii. p. 494. 



Hab. Australia and New Zealand. 



Three excellent figures of this magnificent species have 

 been recently pubUsed by Dr. PhiUippi in his viduable work 

 on Species of Shells ' AbbUd. und Besch. Conch.' for the 

 Haliotis HfBvosa of Martyn, Univ. Conch, vol. ii. pi. 63, 

 from which it diS'ers materially both in form and colour. 

 It was described by Mr. Gray nearly twenty years ago in 

 the work above quoted, and I have had the pleasure of 

 identifying the splendid shell here figm-ed, with a yoimg 

 specimen in that gentleman's private cabinet, having the 

 name of Mr.AUan Cunningham, the indefatigable Botanist 

 of that Expedition, attached to it in Mi'. Gray's hand- 

 writing. It is a very large thinnish concavely flattened 

 shell, mth the left side rather shai-ply angulated, and the 

 outer sm-face finely sculptm-ed tlu-oughout with \vi'mkled 

 striae, a good distinctive character to which I attach some 

 importance, and which is conspicuously developed in spe- 

 cimens of different stages of growth now before me. The 

 coloui- is a light rusty red, variegated with flamc-likc patches 

 of dark brown, with a little gi-een intermingled, the nacre 

 of the interior being of a rather pallid hue.
